Natural FGUI with personalised accent
Primary actions, focus states, selected surfaces and readable accent ink all follow the generated Light recipe.
Horizontal hue control
Personalise the FGUI interface accent
Choose only the hue. FG UI keeps saturation, lightness, contrast and Light/Dark recipes controlled so the interface stays recognisably FGUI.
Accent colourDrag left ↔ right only
HEX entries are normalised to their hue. FG UI deliberately does not expose free vertical saturation/lightness movement.
Theme matrix
One accent, every theme mode
Switch themes after changing the hue. The same preference derives readable Light and Dark recipes automatically.
Dark recipe generated from the same hue
Accent ink becomes lighter while soft surfaces and borders become darker, without asking the visitor to choose a second colour.
Theme-aware accentThe same hue remains readable on this local Dark surface.
Rules
Personalise interface colour, not the brand
Horizontal hue only
The slider cannot move vertically. FGUI owns saturation/lightness and accessibility.
Generated palette
Primary, hover, active, soft, border, ink and focus recipes are generated together.
FG Blue remains canonical
--fgui-brand* is not changed. Reset instantly returns interface accents to FG Blue.
